Forty-five breweries and more than 100 craft brews will be featured at the fourth annual New Hampshire Brewers Festival, happening Saturday, July 22, at Kiwanis Waterfront Park in Concord.

The brewfest, hosted by the New Hampshire Brewers Association, spotlights New Hampshire brewers exclusively and has the largest collection of New Hampshire breweries at a single event this year.

“The whole festival is put together by actual brewers for true craft beer lovers,” NHBA Executive Director CJ White said. “It’s a true celebration of New Hampshire craft beer and brewers and the industry in the state.”

The lineup includes brewers from all over the state, many of them returning, but there will be some newcomers. For recently opened breweries such as Rek’-Lis Brewing Co. of Bethlehem, Sublime Brewing Co. of Plymouth and Backyard Brewery of Manchester, this will be their first ever brewfest.

Most of the booths will be manned by the breweries’ own brewers and staff.

“These aren’t just volunteers pouring,” White said. “This is a chance to meet and talk with the New Hampshire brewers themselves. Everyone who is pouring can tell you more about the beer in depth.”

Additionally, there will be brewers from some soon-to-open breweries including Empty Pint of Dover, Long Blue Cat Brewing Co. of Londonderry, Monadnock Brewing Co. of Keene and Post and Beam Brewing Co. of Peterborough, who won’t be pouring at the fest, but will be in attendance to meet with tasters and talk about their coming brews. There will also be an educational area with booths for home brewing and brewing-related programs offered at local colleges.

“It’s interactive,” White said. “There’s the tasting, but you also have the ability to become more educated and learn about beer as a whole.”

Brewer booths will be lined up under a large event tent. Upon admission, tasters will receive a souvenir tasting glass to use for unlimited sampling.

Each brewery will bring between two and six beers, which may include special releases, collaborations, seasonals or flagship varieties. More than a dozen breweries have collaborated on a project in which they each created a different brew derived from the same base recipe to feature exclusively at the Brewers Festival.

White said she expects to see a number of trending styles represented at the fest as well.

“A lot of sours have emerged, and there’s been a resurgence of some of the lighter beers like kölsch and pilsner,” she said. “And, of course, there will be tons of IPAs for people to try.”

In addition to the beer, the event will feature around 10 different food trucks, brewpubs and other food vendors; music by 92.5/102.3FM The River; a dunk-a-brewer challenge and other activities.
